This is the probably rarest video find of NHRA Championship Drag Racing history. 

Broadcast on ABC's Wide World of Sport, go back in time when Gary Burgin doled out the biggest upset in drag racing history by beating the legendary Don Prudhomme in the Funny Car final round. In Top Fuel, the legendary Richard Tharp shows off his championship mettle. In Pro Stock, the chance to see an AMC Pro Stock driven by Wally Booth match up against Warren Johnson.

However, the must-see in all of this was the Modified final round when Jerry Ault losing an engine on the starting line against Don Coonce. The photos have been largely circulated but up until now, the video has been non-existence.
